To al whom, it may concern.-

Be it known that I, Jnssn ELMER JoNEs, a citizen of the United. States,residing at Sycamore, in the county of Howard and State of Indiana, haveinvented new and useful Improvements in Cultivators, of which the following is a specification.

This invention relates to a rotary harrow or cultivator, and has for itsobjects to pro duce a comparatively simple inexpensive device of thischaracter which in practice will effectually pulveri-ze the soil andremove weeds or other objectionable growths therefrom, one which willnot become choked in action, and one in which the harrow or cultivatorframe maybe readily raised and thrown out of action when circumstancesrequire.

With these and other objects in view the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a perspective View of a harrowembodying the invention. Fig. 2 is a front elevation, partly in section,of the-same. Fig. 3 is a side elevation of the device.

Referring to the drawings, 1 designates an axle provided with eccentricportions or crank-bends 2 and carrying rotary transport ing-wheels 3,arranged for free rotation upon the ends of the shaft, there being fixedto the inner ends of the hubs of said wheels clutch members or sleeves41, while upon the shaft 1 there are mounted for rotation and forsliding movement longitudinally of the shaft clutch members or sleeves5, having at their outer ends clutch-teeth adapted to mesh withcorresponding teeth upon the sleeves 4 and adjacent their inner endsperipheral grooves 6 for a purpose which will hereinafter appear.

Suspended from the axle 1 by means of substantially U-shaped hangers 7is a frame 8, comprising end bars 9 and front and rear connecting-bars10, there being arranged for rotation within the frame a plurality(preferably four) of parallel tubular bars or rollers 11, appropriatelyspaced transversely and equipped with teeth or spikes 12. The rollers11, which have end journals bearing in the frame-bars 9, are preferablyof the form herein shown and each equipped with four rows of teeth 12,projecting from the roller at diametrically opposite points, while thehangers 7 are pivotally suspended within the crank-bends 2 of the axle,thus adapting them for free oscillation and the frame 8 to conformreadily to surface irregularities dur ing the operation of the machine.

The axles or journals 13 of the first and third rollers 11 projectbeyond the outer face of the end bar 9 at one end of the frame and havefixed thereon suitable sprocket-wheels 14, which receive asprocket-chain 15, thus connecting said pair of rollers for simultaneousand uniform rotation, whilethe journals or axles 16 of the second andfourth rollers likewise project beyond the outer face of the bar 9 atthe other end of the frame and carry fixed sprockets 17, adapted toreceive a sprocket-chain 18, whereby these rollers are also adapted forcorresponding rotation, it being noted, however, that all of the rollerswill rotate in the same direction and at a corsponding rate of speed.

Fixed upon the clutch-sleeves 5 for rotation therewith aresprocket-gears 19, one of these gears being connected by a chain 20 witha sprocket-wheel 21, fixed upon the axle of the third roller 11, whilethe other gear 19is connected by a chain 22 with a sprocket-pinion 23,fixed upon the journal 16 of the fourth roller 11, whereby the pairs ofconnected toothed rollers will be driven positively by the respectiveground-wheels when the clutch members4 and 5 are in engagement, there being arranged to bear upon one flight of each of the chains 20 22 anantifriction-roller 24, carried by a substantially lL-shaped member orstandard 25, fixed to and arising from the adjacent end bar 9 of theframe and serving to exert a pressure for taking up slack in the chainand maintaining the latter in proper engagement with the teeth of thesprocketgear and pinion.

Connected with the axle are frame-bars 26, which serve to support atongue or pole 27, having mounted upon its rear end a drivers seat 28.Pivoted to the tongue 27 at a point in advance of the axle 1 is a lever29, connected at its lower end by means of a link 30 with a crank-arm31, fixed upon the axle, this lever being further connected at a pointbelow its fulcrum by a link 32 with a foot-lever 33, pivotally suspendedupon the tongue 27 immediately in advance of the drivers seat, therebeing provided on the lever 33 stirrups 34 to be engaged by the feet ofthe operator, while upon the tongue 27 there is fixed at a convenientpoint a segmental rack 35 to be engaged by a pawl 36 on the lever 29,whereby the lever may, as usual, be locked in its adjusted positions. Itis appar- IIO with yokes 37, adapted to seat, respectively, of theclutch members 5,

in the grooves 6 these rods being slidably mounted at their inner endsin bearings 38, provided at the lower end of a fixed tubularbearing-sleeve 39, carried by and depending from the tongue 27. Arrangedfor rotation within the bearing-sleeve 39 is a vertical actuating memberor shaft 40, having fixed to its upper end an operating-lever 41 and toits lower end a horizontal arm or head 42, the opposite ends of whichare connected, by means of links 43, with the respective rods 36, whileupon these rods are mounted normally ex anded springs 44, bearing attheir inner en supon the bearings 38 and at their outer ends upon pinsor abutments 45, fixed to the rods, these springs serving to force therods normally outward and maintain the clutch members 5 in engagementwith the companion members 4.

In practice, supposing normal active position, as illustrated herein,motion will during the travel of the machine over the ground be wheels 3through the medium of the intermediate gearing to the toothed rollers11, which latter Wlll be driven at a comparatively high rate of speed,thus causing the teeth 12 to thoroughly pulverize the soil. When,however, it is desired to throw the machine out of action, the operatorengages the upper end of lever 29 and releases and swings the latterrearward, as heretofore mentioned, at the same time by means of his theparts to be in transmitted from the 4 feet moving the lower end of lever33 forward, this action serving to rock the axle and swing the frame 8upward, as above described. After the frame has been elevated theoperator grasps the outer end of lever 41 and swings the latter rearwardfor rotating the shaft 40 in the proper direction for acting through themedium of the links 43, to move the rods 36 inward against the action ofthe springs 44 and disconnecting the clutch members 5 from the companionmembers 4, whereby the operating-gearing will be thrown out of action,as will be readily understood.

Having thus fully described the invention, what is claimed as new is Ina device of the class described, an axle having a I air of substantiallyU shaped crank-hen s, ground-wheels journaled on the axle, Ushaped haners pivoted on the latter within the crankends and held thereby againstlongitudinal movement on the axle, a frame suspended for oscillation bythe hangers, a plurality of rollers journaled for rotation in the frameand provided with teeth, sprocket-wheels fixed upon the ends of therollers, a chain connecting said wheels for driving the rollers one fromanother, a chain-and-sprocket connection between one of the rollers andground-wheels, a crankarm fixed on the axle, an operating-leversustained on the machine and connected with said arm, said lever beingoperable for rotating the axleto raise or lower the roller-carryingframe, and foot-levers pivoted on the machine and connected with thearm, said levers having stirrups to receive the feet of the operator formoving the foot-levers to raise or lower the roller-frame.

In testimony whereof I afiix my signature in presence of two witnesses.
